Customs are processed each month to
obtain data on the movement of
merchandise Imported into the United
States. Data obtained include value,
quantity, and shipping weight by
commodity, by country of origin, by
Customs district of entry, and by mode of
transportation.
Import entry documents are required to
be filed for the importation of goods into
the United States. Customs officials
collect and transmit statistical copies of
the documents to the Bureau of the
Census on a flow basis for data
compilation. A 1 % sample of entries Is
processed for shipments valued $250 or
less, which account for less than 1 % of
the total import value.______________
